A certain airplane has two independent alternators to provide electrical power. The probability that a given alternator will fail on a 1-hour flight is .02. What is the probability that
(a) both will fail? = (0.02)^2 = 0.0004
(b) Neither will fail?= (0.98)^2 = 0.9604
(c) One or the other will fail? = 1-(0.004+0.9604) = 0.0392
